In the matter of degraded threads a thread compound can mitigate the factor to a degree.RTV compounds can do double duty,seal coolant migration as well as provide nominal thread support.In my opinion I want the stud in block at no load,so I can control the load on the block threads through the smooth application of torque.Bear in mind,the torque value applied does not put the stud in fully in tension,it is more of a means to set the cylinder head assembly at a consistent compression when cold.
